1. Chinhu chinogodza zvinhu zvisina organic
Chinonyanya kushandiswa iorganic bentonite, iyo ine chikamu chikuru chiri montmorillonite. Chimiro chayo che lamellar chinogona kupa chifukidziro chakasimba chepseudoplasticity, thixotropy, kugadzikana kwe suspension uye lubricity. Nheyo yekukora ndeyekuti hupfu hunotora mvura uye hunozvimba kuti huite hunyoro hwemvura, saka hune hunhu hwekuchengetedza mvura.
Zvakashata ndeizvi: kuyerera kusina kunaka uye kusashanda zvakanaka, hazvisi nyore kuparadzira nekuwedzera.
2. Serosi
Chinhu chinonyanya kushandiswa ihydroxyethyl cellulose (HEC), iyo ine simba guru rekukora, inomisa zvakanaka, inopararira uye inochengetedza mvura, kunyanya pakuita kuti mvura ikure.
Zvakaipa ndeizvi: kukanganisa kuramba kwemvura kwejira, kusashanda zvakanaka kwekudzivirira mould, uye kusashanda zvakanaka kwekuenzanisa.
3. Acrylic
Zvishandiso zvinogonya zveAcrylic zvinowanzo patsanurwa kuita mhando mbiri: zvishandiso zvinogonya zveAcrylic alkali-swellable thickeners (ASE) uye zvishandiso zvinogonya zveAssociative alkali-swellable thickeners (HASE).
Pfungwa yekukora kwe acrylic acid alkali-swellable thickener (ASE) ndeyekuparadzanisa carboxylate kana pH yagadziriswa kuita alkaline, kuitira kuti molecular chain itambanudzwe kubva pa helical kuenda ku rod kuburikidza ne isotropic electrostatic repulsion pakati pe carboxylate ions, zvichivandudza viscosity ye aqueous phase. Rudzi urwu rwe thickener runewo thickening efficiency yakakura, pseudoplasticity yakasimba uye suspension yakanaka.
Chinosanganisa alkali nekuputika (HASE) chinounza mapoka anonyungudutsa mvura zvichibva pane zvinonyungudutsa alkali nekuputika (ASE). Saizvozvowo, kana pH yagadziriswa kuita alkaline, kudzoserwa kwemagetsi pakati pemaion ecarboxylate kunoita kuti cheni yemamorekuru ibude kubva pachimiro chehelical kuenda kuchimiro chetsvimbo, izvo zvinowedzera viscosity yechikamu chemvura; uye mapoka anonyungudutsa mvura anounzwa pachain huru anogona kubatana nezvikamu zvelatex kuti awedzere viscosity yechikamu cheemulsion.
Zvakaipa ndeizvi: kusawirirana ne pH, kuyerera kwakakwana uye kuenzana kwependi, uye zviri nyore kukora mushure mezvo.
4. Polyurethane
Polyurethane associative thickener (HEUR) ipolymer inonyungudika mumvura inonyungudika mumvura inonyungudika, iyo iri yeisina ionic associative thickener. Ine zvikamu zvitatu: hydrophobic base, hydrophilic chain uye polyurethane base. Polyurethane base inowedzera mupendi, uye hydrophilic chain inogadzikana muchikamu chemvura. Hydrophobic base inobatanidzwa ne hydrophobic structures dzakadai se latex particles, surfactants, uye pigments, zvichigadzira network structure ine mativi matatu, kuitira kuti chinangwa chekukora chibudirire.
Inoratidzwa nekukora kwechikamu che emulsion, kuyerera kwakanaka uye kuenzana, kushanda zvakanaka kwekukora uye kuchengetwa kwakasimba kwe viscosity, uye hapana muganho we pH; uye ine zvakanakira pachena mukudzivirira mvura, kupenya, kujeka, nezvimwewo.
Zvakashata ndeizvi: muhurongwa hwepakati nepasi hwekusviba, simba rekudzivirira kugadzikana kwehupfu harina kunaka, uye simba rekukora rinokanganiswa nyore nyore nezvinhu zvinoparadzira uye zvinonyungudutsa.
